Final answer:
Troodontids have relatively large brains compared to their body size, indicating a higher level of intelligence. Troodontids do have relatively large brains compared to their body size, making statement A. True. Their brain-to-body size ratio was similar to that of some modern birds, indicating a higher level of intelligence.
Step-by-step explanation:
Troodontids do have relatively large brains compared to their body size, making statement A. True. Troodontids were a group of small, bird-like dinosaurs that lived during the Late Cretaceous period. Their brain-to-body size ratio was similar to that of some modern birds, indicating a higher level of intelligence. The large brain size of troodontids likely contributed to their advanced cognitive abilities and complex behaviors.
Troodontids are a group of small, bird-like dinosaurs, and they are known for having relatively large brains compared to their body size. This characteristic is often associated with high intelligence among certain dinosaur groups, and troodontids are considered to be among the more intelligent dinosaurs.
